This study examines how disparities and inequalities are created, sustained, and accumulated across the life course. In order to understand the dynamics behind inequality of educational opportunities, the attainment of occupational status and income across the life course, we have conducted a longitudinal survey of the youth and the middle-aged individuals. This has enabled us to trace the trajectories of the same individuals over the years. The survey data set is made available to the public by the Social Science Japan Data Archive for academic purposes.

We announce the outcomes of our research project in an annual press release. The NHK national broadcasting network, the Asahi Shimbun, the Yomiuri Shimbun, The Nikkei, the Financial Times, the New York Times, and other media outlets featured our research results. The members of our research project presented papers at the meetings of the Japan Sociological Society, the Japan Society of Educational Sociology, the Japanese Association for Mathematical Sociology, the International Sociological Association, and the American Sociological Association. The members also contributed articles to professional journals both in Japanese and English. The most recent publication is the three volume series entitled Cumulative Advantages and Disadvantage among Young People (in Japanese) by Keiso Shobo publisher.
